28.2.37 Port L Pull-Up Control Register (PLPUPR)
PLPUPR is an 8-bit readable/writable register that performs the pull-up control for each of the port
L7 to L0 (PL7 to PL0) pins when the port L pins are used by peripheral modules. When the port L
pins are used by the GPIO, the setting for this register is ignored.
